中风步态44例临床分析

Clinical Evaluation of Gait in 44 Patients with Stroke

本文应用临床步态分析方法,测定了50例健康中老年人。44例中风患者的时间距离值(TD)。结果表明,中风病人与健康者TD值差异显著。作者认为,中风病人的治疗目标应以其本身TD值结合功能分级为基础较妥;所测量的7项参数中,步速、步角、步宽这三项参数尤为重要。

In this article we compared the temporal-distance (TD) gait values of 50 middle-aged healthy subjects with those of 44 patients with stroke. All patients were divided into four grades or three groups according to Massachusetts General Hospital Functional Ambulation Classification. Stride length, step length, cadence, velocity, foot angle, foot width and ratio of stride length to lower extremity length (SL: LEL) were measured. According to the results of our series, it is suggested that gait assessment goals for stroke patients should be based on their values and on functional ambulation classification instead of those of healthy subjects. The functional category was related significantly to most of TD values. Of the seven TD values examined, velocity can reflect the quantitative changes of gait, whereas foot angles and foot width mean qualitative difference in gait. Therefore the three factors are especially important among TD values.
